O N' STEWART, or to xnesr, ALABAMA- SQ H IP -COALINGaDEVICE, i

To all whom it may concern:

Be it known that I,JOHN S; STEWAR a citizen of the United States, andresiding at Lockhart, in the county of Covington and State of Alabama,have invented certain new and useful Improvements" in Ship-CoalingDevices, of which the following is a specification.

The present invention relates tothe 'class of loading and unloading andhas particular reference to'new and useful improvements in ship-coalingdevices.

The primary object of my invention is to provide new and usefulimprovements in coaling devices 'forships when at sea without thenecessity of cable or other unreliable conveying apparatus between acollier' or the like and a ship to be coaled.

Another object of my invention is to provide a ship-coaling device oftheclass described which may bebuilt in or permanently associated with acoal carrying ves-. sel such as a barge or the like, the loadingmechanism having suitable driving means associated therewith whichintthe present instance is preferably an electrical motor.

A further object of my invention is t6 provide means carried on acoaling ship whereby the delivering vessel may bemaintained at asuitablesafe distance from the receiving vessel at the sameltimeaffording quick transfer of the' cargo with the least amount of weight.

Other objects and advantagesto be derived from the use ofniy imprQvedcoaling ship will appear fromthe following detailed description and theclaim, taken with the in:

spection of the accompanying drawing in Which i T T Figure 1 is a topplan view of my improved coaling shipand the: coal conducting mechanismshowing the same inoperative position. a p J Fig. 2 is a longitudinalsect onal view taken on the line 22 of Fig. 1 looking in the directionof the arrows, and, i Fig. 3 is a transverse sectional view taken on aline 3 3of Fig. 1 looking inth'e direction of the arrows.

Referring more particularly to the draw ings, wherein similar charactersof reference designate like and. corresponding parts throughout'thevarious views, 1 designates the hull of my improved vessel having theusual'bottom 2- and sides 3. The1hul1 l is. provided with fore and aftholds 4 and 5, v

respectively. The vessel may be used as a barge or lighter for towingpurposes or may be self-propelled, in which event the holds 1 andb maybe employed for containing propelling machinery, crews quarters, etc.

The hull of the vessel is provided with the usual weather deck 6, theforward portion of the weather deck being provided with a hatch 7,closed by a door 8,covered by a protecting grating 9. An upper deck 10is an ranged transversely of the vessel, preferably a little forward ofthe midship section and a platform 11 is supported thereabove, saidplatform and deck being strengthened by a block 12. The hoistingmechanism of my in vention is carried on a pair of vertical stand: ardsl3 and 14- extending from the keel of the vessel to a suitable pointabove the plat- I provide driving means for the conveyer.

16, said means in the present instance comprising an electric motor 27the armature shaft of which is extended as at 28, mounted in a bearing29 and having a pinion 30 there on for engagement with one of the chains17 of saidconveyer. In order to equalize the driveon the conveyer 16 Iprovide a countershaft 31 mounted in a bearing 32 and having-pinions 33on its free ends for engage ment with the first mentioned pinion 30 anda pinion 34 carried by a stub-shaft 35 mounted in a bearing 36, the lastmentioned pinion being in engagement with the other chain of theconveyer 16.

, I provide a coal containing hopper or the like which is preferablylocated aft of the conveyer mechanism hereinbefore described, saidhopper being designated 37 and having an inclined bottom wall 38, theinclination of the bottom 38 being forwardly of the ves-. sel. Aplurality of openings 39 are provided in the bottom 38, said openingsbeing normally closed by sliding 'doors 40. "A

vened for this purpose.

It will be readily apparent from an in' spection of Fig. 2 that thebuckets 18 pass through a suitable opening 43 provided in the bottomwall 38 of the hopper 37. In

order to convey the contents of the hopper 37 to the buckets, I providea conveyer, preferably of the endless type, designated 4st and beingtrained over rolls 15 and d6 7 mounted in a suitable frame 47 beneaththe openings 39 hereinbefore referred to. The convcyer 4% ends at apoint proximate to the path of travel of the buckets 18 whereby toconvey the contents of the hopper 37 to 7 said buckets as desired.

Necessarily, the conveyer 4A must have some driving means and I thereforprovide the driving chain I8 trained over a sprocket 49 operativelyassociated with the rollers 45. said chain being further trained over anidler 50 carried by one of the standards, and thence over a powerreceiving sprocket 51 carried by the same standard, inthe presentinstance the standard 14 I11 order to drive the sprockets 51, I providea pinion 52 mounted on the shaft 53 and rotatable with the saidsprockets, said pinion 52 meshing with a relatively large gear 54:carried on one of the shafts 25, the shaft being length- A hearingbracketis provided for the shaft 53 and'the extended portion of one ofthe shafts 25.

I provide a coal deck 56 having outwardly inclined portions .57, whichportions are provided with coal directing flanges 58, whereby to conveythe coal to the delivery chutes 59, arranged in a novel lDOHlltll'lghereinafter described.

I provide means for emptying the buckets 1S automatically as the samereach a predetermined point on the coal deck, said means preferablyembodying a trip member 60 pivoted'at 61 in a bracket62 mounted on thecoal deck. A coil spring or the like 63 serves to normally tend tomaintain the trip 60 in the lower position, a set screw 64% serving toadpist said trlp to the desired height. The conve ver arcferabl travelsin a i y the direction indicated by the arrow in Fig. 2. and it will beseen as the buckets pass the trip the former are tilted as indicated toadvantage in Fig. 2 emptying the contents thereof on to the coal deckand thence to the chutes. 7

In the present instance, I have shown in Fig. 1 two receiving vesselsdesignated 65 and66, said vessels having the usual hatches (37 formingthe entrances to the coal bunk-' ers. In order ,to adjust the chutes 59to the desired height, I provide brackets 68 Copies of this patent mabeobtained for 7 hereto.

carried by the upper ends thereof. 'The brackets 68 are formed toprovide rack bars 69 arranged in meshing engagement with pinions 70carried on brackets 71 mounted on the deck 10. Cranks 72 carried'withthe 7 'pinions serve to rotate the latter for raising and lowering thechute. I do not limit myself to the showing disclosed in the drawing inso far as the chute construction and adjustment is concerned, but I dolay particular stress upon the novelreceiving and conveying mechanism aswell as the arrangement of the conveyer 4 1 in. the hopper 3?,

In order to prevent contact between the collier and the vessels to becoaled I pro vide fenders 73 mounted as at 74 on the sides of thecollier, said fenders being adjustable in height by means of cables '75framed over drums 76 operable by cranks 77.

From the above description taken in con nection with the accompanyingdrawings,

it is thought that a clearand comprehensive understanding of theconstruction, operation and advantages of my invention may be had, andwhile I have shown and de scribed my invention as embodying a specificstructure, I desire that it be understood that I may make such changeson said struc tures as do iiotdepart from the spi'rit'and scope oftheinvention as described.

. What I claim as new and desire by LettersPatent is V A loading deviceof thecharacter described, comprising in combination. with a ship havingits deck inclined and formed with a series of discharge openings, ofdoors for normally closing said discharge to secure openings, inclinedconveying means arranged beneath said openings and extend inglongitudinally of said inclined portion of the deck, vertically disposedconveymg means including a series of buckets communicating with the hullof the ship and havinga horizontally disposed stretch at a point abovethe deck, said vertically dise posed conveying means communicating withthe inclined conveying means whereby to permit the discharge of matterfrom the inclined conveying means thereinto, means in the path of thebuckets on the horizontal stretch of said conveying means for trippingthe buckets at a predeterminedpoint and causing the dumplng of thecontents thereof, laterally inclined chutes arranged on the ship:atopposite sides of the horizontal stretch of thevertically disposedconveying means,'and means for vertically adjusting the chutesindependently ofeach other. 7 1 i In'testiinony whereof I aflix mysignature JOHN s. screw- RT.
